'Legends Of Tomorrow' Season 2 Episode 17 Spoilers: Heroes Find Unlikely Allies To Face Legion Of Doom In Finale 'Aruba'

The latest episode of the second season of "Legends of Tomorrow" certainly concluded with a shocker, but it looks like there are more jaw-dropping moments in the season finale. The Legends might still be dealing with the loss of Amaya, but at least they have a plan to prevent the Spear from being taken in the finale "Aruba". But who can help them defeat the Legion of Doom in "Legends of Tomorrow" Season 2 Episode 17?

In "Doomsworld", viewers got a glimpse of the future being ruled by the Legion of Doom, as per TVLine. The Legends attempt to take the Spear once again but are stopped by Snart, who froze Amaya and blew her to icy bits. Defeated but still hopeful, the survivors decide that they have to go back to 1916 to make sure that the Spear will not be stolen. However, it is revealed that Rip and the Waverider are actually in Eobard Thawne's lab, where it happens to be a miniature display. So who can the heroes turn to for help in "Legends of Tomorrow" Season 2 Episode 17? What is the cardinal sin of time travel that they will need to break in the season finale "Aruba"?

According to ComicBookMovie, the Legends might need to reach out to their younger selves to make sure that the Spear is never taken. It certainly sounds like something could go wrong if they make even the slightest mistake. Will the heroes prevail and perhaps save Amaya from death in "Legends of Tomorrow" Season 2 Episode 17? What role will Laurel Lance play in the exciting season finale?

CeleBeat has previously reported on the possibility that Laurel Lance will be resurrected in "Aruba". However, it looks like Katie Cassidy's Black Canary will be reunited with sister Sara in the past. Hopefully, there will be plenty of action as the two Canaries work together in the season finale. "Legends of Tomorrow" Season 2 Episode 17 will air on The CW on April 4.
